nnnnCleaning bi-directional flow and
nnnnanti-acid filter driers (liquid line)
nnnn* DDNCY (Temporary use)
nnnn■ Applications
nnnnDTGB - 2.5-1-1-10
nnnn01/10
nnnn■ Cleaning and decontamination of refrigerant circuits in
nnnnrefrigerating and air conditioning installations with change over
nnnnin flow direction, including heat pumps.
nnnn' Temporary uses:
nnnn-»new installations during start-up period for a very efficient
nnnnprotection of compressors against all types of dirts.
nnnn-» existing installations for an efficient cleaning of the refrigerant
nnnnafter compressor burnout.
nnnnFunctional features
nnnn•Products are compatible with HFCs, HCFCs, CFCs, as well as
nnnnwith their associated oils and additives. Products are designed
nnnnfor use of non-hazardous refrigerants from group 2 of PED
nnnn97/23/EC.
nnnn•Product classification in CE categories is performed using
nnnnthe PED 97/23/EC table, corresponding to a volume-based
nnnnselection.
nnnn•Refrigerant flow is possible in both directions, and filtering is
nnnnensured whichever the direction.
nnnn•Filtering at outlet preventing propagation within the circuit of
nnnnparticles bigger than 12 microns.
nnnn•Two Shraeder valves for checking pressure drop, which
nnnnfacilitates the monitoring of filter saturation (except for model
nnnnDDNCY 083).
nnnn» No desorption, even at high temperatures.
nnnn•Easy installation, in the liquid line between the condensing unit
nnnnand terminal units (evaporators or air conditionning indoor units).
nnnn■ CARLY advantages
nnnn> Bi-flow cleaning filter driers with very low pressure drop,
nnnnthanks to an innovative CARLY patented system, in
nnnnterms of flow circuiting.
nnnn> Great efficiency for acid, wax binding and oily sludge
nnnnneutralization at all temperatures, thanks to a fair
nnnndistribution of chemical agents present in the filters:
nnnnmolecular sieves, activated alumina, active charcoal.
nnnn'Chemical agents in the form of free grain, for
nnnnincreased performance and elimination of the risk of
nnnnpolluting the circuit with solid particles, consecutive to
nnnndrying core break-up.
nnnn> No risk of discharge of the pollutants trapped inside the
nnnnfilter driers, during change over in flow directions.
nnnn'Very economical cleaning process with no loss of time,
nnnnbecause the installation is still running during the
nnnnoperation.
nnnn■ Environmental protection and savings of refrigerant,
nnnnbecause using these cleaning filters allows re-use
nnnnof the refrigerant after pollution control.
nnnn> GOST certified products.
